[PATCH 4/4] ARM: at91/dt: sama5: move NAND nodes into board dts/dtsi

sama5d3 and sama5d4 SoCs provides several CS to interface with external
memories, and in particular NAND chips.
The NAND flash controller embedded in the these SoCs can connect to any of
the available CS (each CS is assigned a memory range, hence the nand at xxx
you're seeing in the DT), thus the NAND chip definition should be part of
the board description because we cannot guess at the SoC level which CS
will be chosen by the board designer.
